ABSTRACT
Iru is a food flavouring condiment that is
derived from fermentation of mung bean. These fermented food condiments are
known to be a good source of diatery protein and vitamins. Most diets of
Nigerians are lacking in fairly large amounts of protein due to the high cost
of accessible protein. The high cost and inadequate supply of animal proteins
and other nutriehts have necessitated contemporary research, geared towards the
utilization of protein from underutilized high protein legumes such as mung
bean seeds. The processing steps includes, harvesting, sorting/cleaning,
soaking, cooking, dehulling, with fermentation playing a significant role along
the process through the activities of microorganism. The findings will be of
great value to the masses by bringing to their awareness the nutritional value
ofiru from mung bean and soy bean. The pH, proximate, mineral, phytochemical,
amino acid, volatile constituents and sensory quality of iliru” produced from
dehulled and undehulled mung bean were comparatively evaluated using iru from
soy bean as control. The pH showed an increase from initial 6.13 in unfermented
mung bean to an alkaline pH of 7.24 and 7.67 at the end of 96 hours in iru from
dehulled and undehulled mung bean. The moisture, protein, fat, flavonoid,
alkaloid, tannin and phytate content of the iru samples ranged from 29.66
(dehulled mung bean) to 22.55% (control), 39.15 (control) to 25.84% (undehulled
mung bean), 30.61 (control) to 14.92% (undehulled mung bean), 9.22 (undehulled mung
bean) to 2.16 mg/100 g (control), 4.37(undehulled mung bean) to 1.06 mg/100 g
(control), 2.13 (undehulled mung bean) to 1.05 mg/100 g (control), and 68.25
(undehulled mung bean) to 31.10 mg/100 g (control) respectively. Fifteen amino
acids were detected comprising both the non-essential and the essential amino
acids. Lysine, leucine, valine and phenylalanine generally had the highest
amounts (5.25, 7.15, 4.18, and 5.14 g/100 g) in the iru samples as compared to
other essential amino acids. Higher values were obtained for aspartic acid,
arginine and glutamic acids. Thirty two volatile compounds were detected in ail
the iru samples. Seventeen volatile compounds were identified in iru from
dehulled and undehulled mung bean respectively, while fifteen was identified in
iru from soy bean. There was no significant (P>0.05) differences in the
amount of each volatile compound identified in dehulled and undehulled iru from
mung bean, but significant (P<0.05) different existed between iru sample
from soy bean. The sensory properties showed that iru from dehulled mung bean
could compete favourably well with iru from dehulled soy bean (control) in
terms of consumer acceptability, whereas iru produced undehulled mung bean were
the least preferred by panelist. From the result obtained from the research, it
can be conclude that iru should be produced from dehulled mung bean as this
will reduce the over dependence on soy bean and enhance the utilization ofmung
bean.
